Title: Plug fall preventer for optical connector
Inventor: ISHIDA KIYOSHI
IPC: H01R13/639
Filed: 1989-07-17
Abstract: PURPOSE:To reinforce the connection of optical connector plugs and prevent them from falling owing to the mechanical vibration of an optical connector terminal plate by fitting an 8-shaped elastic beltlike member onto the clamping nuts of the two optical connector plugs. CONSTITUTION:The elastic beltlike member is fitted in an 8 shape onto the clamping nut parts 2a and 2b of the two optical connector plugs 1a and 1b. Consequently, if one clamping nut part 2a becomes loose to rotate counterclockwise, the elastic beltlike fall prevention member 4 applies the other clamping nut part 2b with a clockwise rotational force for clamping the clamping nut part 2b. Therefore, the two optical connector plugs la and 1b do not become loose. Consequently, the clamping nuts 2a and 2b of the optical connector plugs 1a and 1b are prevented from falling due to going to loose.

IPC: H01M8/02
Filed: 1986-08-04
Abstract: PURPOSE:To store extra electrolytes and to absorb a volume change in the electrolytes without flooding by making a gas separation plate be composed of a dense layer, and porous parts and dense parts which are formed on both surfaces of the plate. CONSTITUTION:A fuel gas and an oxidizer gas are supplied to gas flow paths 11 and 12 formed perpendicularly to each other from porous parts 14, 15 and dense parts 16, 17 which are formed on both surfaces of a gas separation plate 18. The dense layer 13 of the gas separation plate 18 functions to prevent the mixing of the fuel gas and the oxidizer gas which flow on both the surfaces of the plate 18. When both the gases advance to catalyst layers 6 and 7 of electrodes 2 and 3, they are ionized and their reactions occur through an electrolyte matrix 1 and so power generation occurs. Excessive gases and vapor gases as reaction products are exhausted through the gas flow paths 11 and 12. Electrolytes together with the vapors are exhausted outside. Therefore, although the electrolyte matrix 1 and the catalyst layers 6 and 7 become short of electrolytes on their long-term operations, they are replenished with electrolytes impregnated in the porous parts 14 and 15 of the gas separation plate 18.

Filed: 1987-07-22
Abstract: PURPOSE:To suppress the vibrating transient current at switching by conducting a transistor(TR) having a large drive resistor at first and conducting a TR having a small drive resistance when an output level is close to a final level. CONSTITUTION:When a level of an input signal changes from a low to a high level, TRs P1, P2 are changed from ON to OFF at first and TRs N1, N2 from OFF to ON. Moreover, the TRs P1, N1 have a large drive resistance. In response to the change, the TR P5 changes from OFF to ON and the TR N5 changes from ON to OFF. In this state, a charged electric charge in a capacitive load CL is started to be discharged via the source and gate of the TR N1. As the discharge is progressed, the TRs P3, P4 change from the OFF to ON and the gate potential of the TR N6 with a small drive resistance rises and the TR N6 is turned from OFF to ON.
